This layered architecture is built by the aragonite platelets which are glued by the biopolymer with a volume fraction of 5%. Inspired by the relevance between the microstructure and properties of nacre, various building blocks such as nanoclay, carbon nanotube and graphene oxide can be used to construct nacre-like layered structure. Besides, applying multiple interface interactions, synergistic effect from interface interactions as well as building blocks can be achieved leading to high-performance polymer nanocomposites. The bioinspired strategy to fabricate polymer nanocomposites opens up a new avenue for future research work and broadens the application of polymer nanocomposites. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
